Application led September 24, 1917. Serial No. 193,007.

To all whom it may concern:

Be it known that 1, FVAN BARNETT BAsoH, a citizen of the United States of America, and a resident of Savannah, county of Chatham, and State of Georgia, have invented certain new and useful lmprovements in Phonograhpic Dictating-Machines, of which the following is a full and clear specification.

My invention relates to dictating machines and more particularly to devices for automatically indicating upon a record when an error in dictating has been made.

In dictating machines of any make words recorded on the wax cylinder cannot be changed, or erased, so if an error in dictation is made, the dictator must afterward speak the corrected words, and some signal must be given to the typist, so he 'will know an error has been made at a certain pointe-n the cylinder, and will then be able to determine the correct words totranscribe.

At present this is ordinarily accomplished by providing a printed card with a scale corresponding to the progress of the recorder I across the cylinder so that a pencil mark or check at a point 4on the card will call attention to a correction at a corresponding point on the cylinder.

On the Edison dictating machine for instance, the printed card is placed in a holder which travels with the record, and a 'short rule fixed to the machine at right angles to the path of the card automatically indicates on the card the position of the recorder on the cylinder, consequently when an error has been made in dictating the dictator `draws a line across the card Aat the point where the fixed rule is, thereby indicating that an error has been made at that point.

- Various other similaredevicesV are in use on other makes of machines but in every rereading a portion of thefcylinder to find'` case the dictator is obliged to stop and make some mark on the record card indicating the error. This is not only an annoyance and a loss of time but it ofttimes causes him to lose the thread of thought and necessitates him 2 2 of Fig. 1.1

Hence it willV 'be seen that the dictator will cluding a fixed record card and the marker as being secured to the recorder and moving therewith but it is obvious that the record` card may be fixed to the recorder and the marker stationary.

rIhe invention will understood by reference to the and drawings, in which Figure 1 is a plan view of a dictating machine showing my invention attached.

be more thoroughly specification Fig. 2 is a transverse section taken on line Fig. 3 is a fragmentary view `partly in section, of the end of the speaking tube.

Fig. 4 is a detail sectional view of the record card and attaching means.

Fig. 5 is a diagrammatic view of the device; and Fig. 6 is a detail view of a modified form of any device. f

lrllhe numeral 1 represents the ordinary soV dictating machine of the Edison type and 2 the usual cylinder upon which the dictation is recorded.y The recorder 3 hasthe usual tube 4L terminating in a mouth-piece 5 and having secured near the mouth-piece a finger grip 6, and the cylinder controlling button 7 As is customary in machines of this kind the recorder 3 during its operation of recording moves to the right of the cylinv matically marking the record card as secured tothe recorder and comprising a solenoid 8 having a movable core 9 provided with an extension 10 for holding a suitable Y- pencil 11.

'llo` normally keep the core in'its extended position 1 provide a spring12 bearing against a collar 13 formed on the extension 10 and the face of the solenoid. By this construction it will be seen that when the solenoid is energized it will attract the core and draw it inward compressing the'spring 12 between the collar 13 and the face of the solenoid and move the marker in a correder hence 1 have shown the device for autol sponding direction across the record card, y thereby indicating that at that point an error has been made.

I can secure'the solenoid to the recorder in any suitable manner but I have shown the securing means as comprising a metal strap 14 shaped to circumferentially secure the solenoidv and then clamped around the recorder by means of a screw 15. p

The record card is here shown as a cel,-

lular card 16 secured by suitable 'supports 17 and screws 18 at each end to the frame 19 of the machine as shown.

The solenoid may be energized by any source of power. It may for instance be connected to the motor circuit or it may be supplied by a separatesourceof power S, as indicated diagrammatically in Fig. 5. rlhe erably adjacent the finger grip 6 is a switch adapted to close the circuit between the solenoid and the source of power. This switch is shown as comprising a contact 21 and a spring held contact 22 provided with an operating button 23. The switch is normally open but when it is desired to energize-the solenoid it is only necessary for the dictator to press the button 23, therebyclosing the circuit to said solenoid.

Fromthe foregoing it is seen that when an error in dictating has been made the dictator need only close the circuit by means of the button 23, thereby energizing the solenoid 8, and consequently drawing the marker 11 across the record card 16 indicating thereby that an error has been made at a corresponding point on .the cylinder. This operation need not interrupt the'dic* maratea 'the marker operator, the core 9a having secured thereto an L-shaped arm 10L carrying at one end thc marker 11a. The. other arm of the L-shaped member is pivoted at 25 to a support 26 securedto the solenoid and is A provided with a spring 27 to normally keep the marker in its extended position. j

It is obvious that various ychanges Vand modi-irati'ons in details of construction may be made wit-hout departing from the scope of my invention.

What I claim is z- 1. In a dictating machine, a record card,

`a marker, a solenoid, means for normally holding said marker in its inoperative position, and means controllable at a distance for energizing said solenoid and thereby'op- @rating said marker.

2. In a dictating machine, a record card, a marker, means foryvnormally holding said marker in its inoperative position, and means controllable at a distance for operatingvsaid marker. y

3. In a dictating machine, a record card, a marker normally in inoperative position, means for moving said marker into operative position comprising a solenoid and means controllable at a distance for energizing said solenoid. f

4. In a dictatin'g machine, a record card, a marker normally in inoperative position and adapted to be drawn Vacross said record card, a solenoid adapted when yenergized to operate said marker, and means controllable at a distance for energizing said solenoid to operate said marker. V

In testimony whereof I hereunto afiiX my` signature. Y
